About the Airtac SCJ32 Standard Cylinder SCJ32X100-40SN
The SCJ32X100-40SN is a compact double-acting, single-rod pneumatic cylinder with a field-adjustable stroke end. A rear-cap screw provides up to 40 mm of adjustment from the 100 mm nominal stroke, letting you fine-tune the end position without swapping the cylinder. Its 12 mm rod and M10x1.25 knuckle thread suit light-duty positioning tasks.
At 0.5 MPa, this 32 mm bore unit delivers 402 N of push force and 345 N on the pull stroke, with a maximum push of 724 N at 0.9 MPa. The built-in magnet (suffix -S) accepts CMSG/DMSG sensors for end-of-stroke detection, while the NBR seals (suffix N) provide reliable sealing in standard industrial environments. The body length A(SCJ) is 182 mm, slightly longer than a fixed-stroke SC due to the rear adjusting mechanism.
Airtac SCJ32 Standard Cylinder SCJ32X100-40SN Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X100-40SN |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 100 mm |
| Stroke adjustment | Up to 40 mm (rear adjusting screw) |
| Acting type | Double acting (single rod) |
| Port size | PT1/8 |
| Rod thread | M10×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Adjustable, 21 mm |
| Max stroke | Up to 1000 mm |
Specifications follow the official AirTAC SCJ (adjustable-stroke) datasheet. The rear adjusting screw sets the stroke end position; force is the same as the equivalent single-rod SC bore. Confirm against the product label before installation. Thread options: PT (standard) / G.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
SCJ is single-rod, so force matches the equivalent SC bore: push uses the full bore area, pull subtracts the rod area. Actual usable force is lower than theoretical due to friction and back-pressure; size with a safety margin.

Where the Airtac SCJ32 Standard Cylinder SCJ32X100-40SN Is Used
Commissioning & Setup
Quickly dial in the exact stop position during machine commissioning. The 40 mm adjustment range allows fine-tuning of the stroke end without removing the cylinder or adding external hard stops.
Small-Part Diverting
Adjust the divert gate stroke on a packaging conveyor to handle different product widths. The built-in magnet provides reliable end-of-stroke feedback to the PLC via a CMSG sensor.
Wear Take-Up
Compensate for pad or gripper wear in a pick-and-place cell. The rear screw lets operators restore the exact end position in seconds, maintaining consistent part placement without a service call.
Is the Airtac SCJ32 Standard Cylinder SCJ32X100-40SN the Right Cylinder?
Choose the SCJ32 when you need to dial in a precise end position during commissioning or changeover. If 402 N of push force is marginal, stepping up to the SCJ40 provides 628 N at the same 0.5 MPa. For applications where the stroke never needs field adjustment, the fixed-stroke SC32 series offers a simpler, slightly shorter alternative. This model's NBR seals are a good match for standard lubricated or non-lubricated compressed air.
For a direct replacement, match an AirTAC SCJ32X100-40SN with the same 32 mm bore, 100 mm nominal stroke, 40 mm adjust range, PT port thread, NBR seals, and built-in magnet. The basic mounting style uses the cylinder body for direct attachment; if you need a pivoting mount later, the TC centre trunnion with TCM1 bracket is available for this bore.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-40)
- ✓ Required force at your working pressure
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Set the rear adjusting screw, then lock it before running.
- check Adjust end cushion screws for smooth stops.
- check Use SCJ mounting accessory (FA / LB / TC / TCM1).
- check Installation by qualified personnel per AirTAC docs.
Airtac SCJ32 Standard Cylinder SCJ32X100-40SN FAQ
At 0.5 MPa, the push force is 402 N and the pull force is 345 N. The maximum push force at the 0.9 MPa operating limit is 724 N. The pull force is lower because the 12 mm rod reduces the effective piston area on the return stroke.
A screw in the rear cap limits how far the piston can retract, shortening the stroke end by up to 40 mm from the 100 mm nominal maximum. This is a mechanical end-stop adjustment only—it does not change the cylinder's force, speed, or the forward stroke end position.
